Improvement in meat-chopping machines



UNITED STATES PATENT OFFICE FRANK B. FISH, OF MANCHESTER, NEW HAMPSHIRE.

IMPROVEMENT IN MEAT-SHOPPING MACHINES.

Specification forming part of Letters Patent No. 218,869, dated August 26, 1879; application filed February 12, 1879.

To all whom it may concern:

Be it known that I, FRANK B. FISH, of Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Meat- Ohoppin g Machines, of which the following is a specification.

This invention relates to certaim improvements in that class of machines for chopping, hashing, or mincing meat in which a reciprocating cutter-knife or series of knives, arranged to operatein connection with a rotating vessel for containing the meat, is einv ployed; and it has for its object to simplify the construction of the parts, and furnish a cheaper and more effective apparatus than heretofore, and one that is sure in its operation and not liable to get out of order.

To this end my invent-ion consists in the combination, with a double-crank shaft journaled in a suitable frame, of a pitulan secured to one of the cranks, and adapted to operate an oscillating lever carrying `a rod to which the cutter or cutters are attached, and a pawl secured to the other crank and adapted to engage and operate a ratchetwheel secured to the lower end of a vertical shaft, to the upper end 0f which is secured a carrier adapted to receive and rotate, at proper intervals, the vessel which contains the meat, the crankshaft being provided with suitable gearing, by which motion may be imparted to it.

`In the drawings, Figure l represents a side elevation of my improved apparatus; Fig. 2, a horizontal sectional view on the line a m of Fig. 1, and Fig. 3 a longitudinal vertical section of the apparatus. Fig. 4 is a perspective view of the meat-holding vessel detached.

The letter A represents a frame of suitable construction, consisting, in the present .instance, of a rectangular casing. This frame or casing may be made of any desired material, but, on account of cheapness and convenience, is preferably made of cast metal.

The letter B represents a double-cran k shaft, extending transversely across the frame, and

journaled in opposite sidesthereof, said shaft' passing through the frame'at one end, upon which is mounted a pinion, C, which intermeshes with a driving gear-wheel, D, by which motion is imparted to it. To the crank b of said shaft is pivoted the lower end of a pitman, E, the upper end of which lis pivoted to an oscillating lever, F, fulcrumed in the upper end of a standard, G, rising from the rear of the frame A. The forward end of said standard has pivoted to it a beam, H, to the lower end of which are secured one or more cutting-knives, I.

The letter K represents a vertical shaft extending through a bearing, L, in the upper part of the frame A, and a bearing, M, in a transverse bar, N, extending across said frame below. To the lower end of said shaft is secured a ratchet-wheel, P, with which is sel T, in which the meat is held, and subject it in the proper varying positions to. the action of the cutters. Said rotating cylinder is adapted to be detachably secured in the carrier, so that it can be removed and readily replaced when desired, for thepurpose of cleaning. In Fig. 4 this cylindrical vessel is shown as removed from the carrier S, into which, when in use, it fits so closely as to be held in place by friction.

What I claim is- In an apparatus for cutting, hashing, or

mincing meat, the combination, with the double-crank shaft, of a pitman secured to one Y of the cranks of said shaft, and to an oscillat ing lever above, carrying the cutting-tool, and a pawl secured to the other crank, and adapted to engage and operate a ratchet-wheel on a vertical' shaft, having mounted on its upper end a carrier adapted to receive and. rotate the vessel containing the meat, substantially as and for the purposes specified.

In testimony that I claim the'foregoing I have hereunto set my hand in the presence of the subscribing witnesses.

- FRANK D. FISH.
